DUMP WAGON.

Application filed January 6, 192-2, Serial No. 527,413. Renewed April19, 1923.

To all whom it may concern:

Be it knownthat I, Josnrn GAssnn, a citi zen of the United States,residing at Trenton, in the county of Mercer and State of New Jersey,have invented new and useful Improvements in Dump Wagons, of which thefollowing is a specification.

This invention relates to dump wagons and more particularly to that typeor form of such wagons which is motor driven, means being actuable bythe motor thereof to effect the tipping of the dump-box or body todischarge the contents whilst said dump-box or body can be promptlyreturned thereby to its normal position.

The primary object of this invention is to provide a novel mechanism forpromptly raising and inclining the dump-box or body portion of a dumpwagon from its normal position on the chassis or underframe, and viceversa.

Other objects of this invention are the provision of a simple, strongand very effective means for inclining a dump-wagon body portion of boxrelative to its supporting frame or chassis, saidmeans being operable bythe wagon motor. 1

With the foregoing and other objects in view this invention consistsessentially in the novel features of construction, combinations andarrangements of parts hereinafter fully described and more specificallydefined by the appended claims.

In the further disclosure of the invention reference is to be had to theaccompanying sheets of explanatory drawings constituting a part of thisspecification, and in which like characters of reference designate thesame or corresponding parts in all the views. p Figure 1 is a sideelevation showing the application of my invention to a motor drivendump-wagon, the dump-box or body portion being shown in itsinclined ordump- 7 thereof, all of saidparts being in accordance with the wellknown structures of such vehicles and forming no part of this invention.

According to my invention the dumpbox or body 7 is supported on rigidlyconnected longitudinal and opposed channels 8, 8 adapted to normallyseat on the underframe 9 that is appropriately mounted on the chassis41. In ,order to provide asuitable hinge connection between the dump-boxor body 7 and the chassis l secure to said chassis a at its rear end apair of brackets 10 in which is journaled a transverse shaft 11 the freeends whereof are suitably fixed to the aforesaid opposed channels 8, 8and it will be easily seen from Figure 1 that said manner of connectingthe dump-box or body 7 to the underframe 9 provides a very strong andserviceable means whereby any lateral displacement of the formerrelative to the latter is effectively prevented.

Appropriately journaled transversely beneath the dump-box or body 7between the longitudinal channels 8. 8 is second shaft 12 to which areconnected the upper ends of arcuate rack bars 13, 13 that serve aslater' on explained to raise and incline said dumpbox or body 7 Thesearcuate rack bars 13, 13 are adapted to mesh with correspondinglytoothed pinions 1 1, 14: having side flanges 15, of larger diametersecured thereto so that said arcuate racks 13, 13 are protected againstlateral displacement and tor-- sional derangement. The aforesaid toothedpinions 14, lf are keyed or otherwise securely mounted on a transverseshaft 16 journaled in a duplex forked bearing 17 mounted in and securelyattached to the 95 chassis 4:. On an examination of Figure 2 moreparticularly it will be seen that the duplex forked bearing journalportions 18 are upwardly extended to provide additional journals 19 forstub axles 20' having 100 anti-friction flanged rollers 21 adapted toengage that edge opposed to the toothed by those acquainted with theart, to which my invention appertains.

In. the form of my invention shown by Figure 1 it will be seen that theshaft 16 is provided With a Worm-Wheel 23 enclosed in an appropriatehousing 24, and said Worm- Wheel 23 is rotated by a Worm 25 on alongitudinal shaft 26 driven through" suitable clutch gearing from themotor transmission are control lever 28 being provided in the driverscab 29 for engaging; and disengaging said clutch gearing, as will be,clearly, un der stood by those conversant With motorpro- "pelledvehicles. An apropriateknock-out 15 not Sll0Wl1--dCtut1l)l6 by a rod 30is provided for tripping the aforesaid clutch rearing When'the dump bodyor box '7 reaches its maximum elevation and lockingsaid dump body insuch position. v

In the, modified form of the invention 7 shown by Figures Qand 3 it Willbe seenthat' the shaft 16 is suitably journaled 'in an appropriatehousing 24J'inounted on the aforesaid duplex-forked bearing17 and thatit is provided with a pair of spacedspur gears 31 in mesh withcorrespondingly toothed pinionsSZ on a coun'ters'haft 38 that is fitted\viththe Worm-wheel 23 driven by the Worm 25 as hereinbefore described.

Which'is particularly serviceable for use in connection With the heavierservice types of motor driven dump-Wagons. i

Appropriately supported on the housings -24'by a pivot pin 86 or othersuitable advancng means are channel-shaped arcuate members or guides 85'of cross-section correspondstood from an examination of the drawings.

These members or guides areresiliently suspended at their other free endfrom loosely depending contractile springs 34: which are carried fromthe chassis by means I of suitable brackets fixed thereto.

These guide members 35 direct the course of the racl: bars 13 as thebody descends. and encase thejguides protecting them from dust or dirtWhile the spring suspension of the free end of the guide absorbs. theshock con- I I From. the

Still 'further it will'b'e obvious that detail changes may be efiectedand other combina- Thus it' will vbe seen'that a reducing gear isprovided foregoing description and an examination of the drawings, the"operation; and advantages of my novel dump-box ntions of parts evolvedthat will function in precisely the same manner as the embodiments of myinvention hereinbefore out oted beneath and intermediate the ends ofsaid hinged body, an arcuate guide supported from the vehicle, a gearhousing member,
